PlCKER-STAFFCONNECTION FOR LOOMS.

$PECIFICATION forming part of Letters Patent No. 651,? 59, dated June12, 1900.

Application filed January 3, 1900. $erial No. 205. (No model.)

ToaZZ whom, it'm'a y concern:

Be it known that we, JOHN E. HEY and ABRAHAM HEY, citizens of the UnitedStates, residing at Pascoag, in the county of Providence and State ofRhode Island, have invented new and useful Improvements in Picker-StaffConnections for Looms, of which the following is a specification.

Our invention relates to means for pivotally connecting thepicker-staffs of looms to brackets on the loom frames and contemplatesthe provision of a simple and inexpensive connection calculated tofirmly hold a staff without preventing free oscillation of said staffand without causing undue wear of the same and one which is adapted toper-' mit of the staff being readily removed when necessary without theemployment of tools.

With the foregoing ends in mind the invention will be fully understoodfrom the following description and claim when taken in conjunction withthe annexed drawings, in which- Figure l is a broken perspective Viewillustrating a portion of a bracket, a portion of a picker-staif, andourimproved connection. Fig. 2 is an enlarged section with some of theparts partly in elevation, said section being taken in the planeindicated by the broken line 2 2 of Fig. 1 looking in the directionindicated by arrow.

Referring by letter to said drawings, A is a bracket provided with atransverse aperture a and otherwise similar to the brackets usuallyemployed on loom-frames to support picker-staffs.

B is a picker-staff having the usual transverse aperture at anintermediate point of its length.

O is ourimproved connection, which is preferably made up of a sleeve D,a bolt E, a nut F, a washer G, and a thumb-nut H. The sleeve D has acircular end portion 0', which corresponds in length to the thickness ofthe stafli B and is of a diameter to snugly occupy the aperture thereof,a reduced and exteriorly-threaded end portion d, designed to receive thenut F and washer G, an intermediate portion 6 of a size to snugly fitthe aperture of the bracket A, and an enlargement f, arranged betweenthe portions 0 e and adapted to be interposed between the bracket.curely fixed in position.

and staff after the manner shown in Fig. 2,

so as to hold thelatter at the proper distance from the former. The boltE is longer than the sleeve D and is provided at one end withscrew-threads g for the engagement of the thumb-nut H and at itsopposite end with a head 72 fiat at its inner side, asindicated by i.The said head his designed to bear against the face of the picker-staff,as shown in Fig. 2, and thereby hold said staff on the portion 0 ofsleeve D and against casual lateral movement.

It will be noticed that while the head h is calculated to firmly holdthe staff on the sleeve portion 0 it is broad and smooth, and thereforedoes not interfere with or prevent the necessary f roe oscillation ofthe statf, nor

does it dig into and wear the face of the staff.

like the pins usually employed in conjunction with studs in theconnection of pieker-stafis to brackets.

In practice the parts are assembled as shown in Fig. 2that is to say,the portion a of the sleeve is passed into the aperture of the bracket,and said bracket is clamped be tween nut F and the enlargement f of thesleeve, with the result that the sleeve is se After the sleeve is thusfastened to the bracket the picker-staff is mounted on the sleeveportion 0, the bolt is inserted in the bore of the sleeve until its headbrings up against the outer end of said sleeve, and the thumb-nut H ismounted on the threaded'end of the bolt and turned up against the innerend of the sleeve. With this done the picker-stafi will be securely heldat the proper distance from the bracket and against casual lateralmovement and at the same time will be free to oscillate and will not besubjected to undue frictional wear. This latter is due in large measureto the fact that when the thumb-nut H is tightened the bolt-head Itbrings up against the outerend of the sleeve, which preventsit frombinding against the face of the picker-staff.

When it is desired for any reason to remove the picker-stafi, the samemay be readily accomplished without the employment of tools by simplyturning the nut H off the bolt and withdrawing said bolt from thesleeve. It follows from this that the same or a new stafi may be asreadily secured on the sleeve.

Having described our invention, what we claim is.'-,

In a pic'ker 'staffcoiinection for looms, the combination of a brackethaving a transverse 5 aperture, a picker-staif also having a transverseaperture, the sleeve D having the outer end portion. 0,101: circularform in cross-sec tion, arranged in the aperture of the staif, exteriorthreads d at its inner end, the interro mediate portion a resting in theaperture of the bracket, and the enlargement f interposed betweenthebracket and staiflthe bolt E extending through the sleeve and having thebroad, smooth head h at its outer end, bearing 15 against the outer sideof the staff, and threads at its inner side, a nut mounted onthe-threaded inner portion of the-sleeveandi adapted to clamp thebracket against the portion f thereof, and a nut mounted on the threadedinner end of the bolt and bearing against the inner end of the sleeve,substantially as and for the i purpose set forth.
